Maximum Security, one of the favorites, crossed the line first, but after a protest and lengthy review, the stewards ruled that he had impeded the other horses by leaving his lane in the final turn before the homestretch. Maximum Security bumped War of Will, who then hit Country House and it was determined that this action cost Country House a shot at the win.

Mike Tirico explained the ruling for NBC.

"Maximum Security moves off that rail, comes out, impedes the path of War of Will, gets in the way of Long Rainge Toddy and Country House," Tirico said.
